Lightning Data Upgrade - NEW

Lightning Events

lightning Lightning strikes are displayed as crosses (ground events) or squares (cloud events) and fade from white (current) to red (30 minutes ago) to blue (60 minutes ago).

In December 2014 we upgraded our lightning network to the latest in sensor technology as used by the world's leading meteorological agencies. This has resulted in changes and improvements to the lightning data you will now see. The main changes are:

  • Much better detection of cloud to cloud strikes. Our upgraded network detects more CC strikes and better reflects research that shows typical storm cells produce approximately 75% cloud strikes and 25% ground strikes.
  • We have modified the display to show cloud to cloud strikes in smaller boxes and ground strikes above as "+" symbols. Temporal colouring remains the same.
  • Greater network coverage right across the country.

About Weatherzone Radar

distance measuring Distance and latitude/longitude coordinates are displayed when you mouse over the map. The origin for distance measuring is indicated by a red dot and defaults to either your location, if specified and in range, or the location of the radar/the centre of the map. The origin may be changed by clicking elsewhere on the map.

The Port Hedland Radar has an unrestricted 360 degree view with no permanent echoes. During the dry season (April through to December) occasional false echoes occur, generally characterised by small clusters or spots of very low intensity which appear to move at random, mostly over land. During the wet season, thunderstorm clouds and cyclonic formations are generally well defined for distances up to approx 250 kilometres. Beyond that distance signal attenuation gives the appearance of less intensity than possibly exists. These formations are easily identified against false echoes by their regular patterns in movement and direction. It is common in the wet season (primarily January to March) for thunderstorm cells to be seen on almost a daily basis in the area south of Port Hedland. Isolated growing storms can merge to form a line running in a NE/SW direction, located anywhere from 60 kilometres to 200 kilometres south of Port Hedland. Favourable locations for thunderstorm activity as seen on the radar in these events are generally over the ranges south of Port Hedland. During the wet months some anomalous propagation can occur out at sea, however it is generally distinguishable from "real" echoes by random movement and low intensity spots or clusters. Heavy rain directly over the radar site can cause attenuation of all signals. Path attenuation can also occur when the radar beam passes through intense rainfall, with the returned signals from cells further along that path reduced.
